TIMES:

34 hm 3 m & 23 mm x 5 = 170 hm 15 m & 115 mm

a)      We do it in blocks

34 hm

3 m

23 mm

 

x

5

170 hm

15 m

115 mm

 

Or

b)      We convert it in a simplex way and we sort out the times as usual:

3 403 023 mm x 5 = 17 015 115 mm

 

DIVISIONS:

- We convert it directly in a simplex way and we solve it as usual:

34 hm 3 m & 25 mm : 5

3 403 025 mm : 5 = 680 605 mm
